Hi @CaptNob
Welcome To the Community!!
Check out these expressions
Split(System.Text.RegularExpressions.Regex.Replace("_____123_______12,345_____123.45","_+","_"),"_")(1)
Split(System.Text.RegularExpressions.Regex.Replace("_____123_______12,345_____123.45","_+","_"),"_")(2)
Split(System.Text.RegularExpressions.Regex.Replace("_____123_______12,345_____123.45","_+","_"),"_")(3)
If you needed in the array of string use this in your for each and loop through the items
Split(System.Text.RegularExpressions.Regex.Replace("_____123_______12,345_____123.45","_+","_"),"_")
Note: You will receive the first item as empty because your string is starting with “_”
